Discussions of structural racism has now moved to the forefront of the Swedish society, and many researchers have sought to understand what form it takes, how it is manifested, how it is exploited and challenged. At the core of this debate we find the media, and its logic embedded with mechanisms of simplification and polarization.Media is our key source of knowledge and information, why it also affects our norms, beliefs and preconceptions. Media thus has the power to mediate, amplify or challenge how we conceptualize the world, and subsequently our (unconscious) racist beliefs.To investigate how media content is influenced by underlying colonial or racist assumptions and stereotypes thus becomes a way to investigate our understanding of reality.In accordance with postcolonial thought, structural and symbolic racism is embedded in language and hidden in images, and surface in the form of domination and feminization, and the portrayal of the subaltern ?Other? as passive and irrational.This paper thus departs from postcolonial theory and media logic to undercover hidden patterns of structural, symbolic and historically contingent racism in one of Sweden?s most prominent in-depth foreign TV-magazines, namely Korrespondenterna.Adopting Critical Discourse Analysis (CDA), this paper explores to what extent racist and colonial stereotypes are reproduced and/or challenged in Korrespondenterna?s representation of Sub-Saharan Africa.In line with postcolonial theory it is found that historically contingent racialized stereotypes are prevalent in Korrespondenterna, and that tendencies of portraying Africa and Africans as passive, feminine and irrational are prevailing.It is thus argued that media logic, imbedded with mechanisms of simplification, polarization and intensification, contributes to the use of colonial stereotypes in media, and thus to the mediation of structural and symbolic racism..

This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.

The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

Digital artefacts such as smartphones have become an intricate part of our daily lives both private and professionally. They have evolved from doing simple tasks to become a form of expression, as well as acting as a gateway to the digital world of connections. We rely on various technology such as Wi-Fi networks to connect with others. They in turn have become more available and today, many establishments offer free network to their customers. With these developments comes different kind of risks for the user.

The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

The exclusion of visually impaired from the information flow presented to us through signs was what led me into this project. With a growing amount of information being presented to us on signs and digital information surface the need of communicating this information in a way that could be read by visually impaired is evident. Looking into different ways of communication, my goal was to create something that filled the need of the visually impaired without branding them as disabled. Having a close relative with bad eyesight is became evident on how much it limited her in her everyday life, not being able to navigate herself without the support of her husband. Through interviews with her and others with varying diagnoses I reached an insight in their situation. To my surprise they still favored a visual form of communication before an auditory or tactile form, because it?s easy to survey and quick to interpret.

HR yrket är en position som kräver stor spännvidd av kompetenser då de ska tillgodose både ledningen och medarbetarna. Deras yrkesroll är mångsidig då de ansvarar för de anställdas utvecklingsarbete parallellt med pressen att generera goda resultat för organisationsledningen. Många gånger innebär detta motstridiga krav, vilket i vissa fall skulle kunna leda till stressutfall och otydliga roller. Då relativt få studier behandlar HR rollen och dess stressnivå samt rollotydlighet ansåg vi att det krävdes ytterligare dokumentation. Denna studie undersöker samband och skillnader mellan upplevd arbetsrelaterad stress, rollotydlighet och emotionella copingstrategier för HR chefer.

The task has been to develop a holdingsolution that generates force between two rolls and to evaluate the new solution withrespect to functionality, manufacturing, structural stability, costs, assembly etc. Theroll holding solution is a system that is part of a rollpress. The rollpress is used towash and dewater pulp. The existing solution creates forces that have to be absorbedby the gable of the press.

Digitala ytmodeller (Digital Surface Model ? DSM) används ofta i geodetiskt sammanhang. DSM har länge skapats bland annat med hjälp av fotogrammetri där flygbilder har tagits med traditionella flygningar. Intresset tilltar nu för att framställa DSM med hjälp av obemannade flygfarkoster, så kallade UAS (Unmanned Aircraft System). Den största fördelen med UAS är att det går snabbt och enkelt att få den lilla flygfarkosten upp i luften för att ta flygbilder och framställa DSM kostnadseffektivt.Syftet med detta examensarbete var att undersöka vilken höjdosäkerhet som kan uppnås i DSM som framställts genom fotogrammetri med UAS.

Companies and special interest organizations pays multiple millions each year in order to reach out with messages about that their products are biggest, best and most beautiful. The publicity happens among thing like TV, in brochures, on the Internet andin newspapers etc. places. This means that consumer permanently becomes affected of publicity, and is thereby in an exposed situation. Around the EU, the border of what to consider undue or not, have been in different levels.

Incompatibility between donors and recipients can cause fatal hemolytic transfusion reactions (HTR), kidney damage and death and immunization of the recipient. Antigens on the surface of erythrocytes in the ABO blood group system and regular natural antibodies against these in the patient?s plasma must be considered. An individual always has a corresponding antibody of IgM in their plasma. Irregular antibodies acquired by transfusion or pregnancy and active in body temperature also cause the HTR incompatibility.
